Liquid acrylic made with
lightfast fine art pigments

New Colors

Keep it fluid with Liquitex Acrylic Ink, now with 20 new colors including a range of fluorescents. Made with fine art pigments, Acrylic Ink is perfect for layering washes of color, adding in detail with a fine brush, dropping pools of flowing color directly on paper, splatter brushing, and pen & ink drawing.


Pure Pigments

This is a fine art ink. Made with fine art materials. You can rely on the highest quality color-intense artist pigments when you use Acrylic Ink. Our pigments are processed using the latest basket bead-mill technology, where tiny reinforced ceramic beads give fine dispersion, great color development, strength and brightness. No quick-to-fade dyes, just true color purity and archival stability in an ultra-fluid acrylic vehicle.


Liquid acrylic can be used in so many ways. Airbrushing? Pouring? Pen & ink? A sheer wash of color? Acrylic Ink is perfect to use straight from the bottle in any way you want. As our lowest viscosity color, the ultra-fluid formula is ideal for fine and flowing applications and techniques. Add a professional medium to adjust it further.


Each pigment has its own unique natural character and this dictates its opacity. Among the 55 ink colors you’ll find a choice of opaque, semi-opaque and transparent colors - all shown on the label - to help you achieve a range of effects.


Acrylic ink gives you water-resistance and permanence not seen in regular inks. Because it’s acrylic, the ink dries quickly and doesn’t move once dry - which means you can over-paint without bleeding and achieve multi-layered, velvety surface effects. No smudging. 


If it sticks, you can use it. Try Acrylic Ink on:

  • stretched canvas
  • paper & board
  • wood
  • plaster
  • fabric 


On a client’s wall. In a gallery. Your work needs to stay as you intended. As with all Liquitex products, the pigments in Acrylic Ink have passed extensive tests for lightfastness. Each pigment is rated according to the American Society for Testing & Materials (ASTM), and we only use pigments rated ASTM I or II*. This means your work will have the greatest archival permanence possible – at least 50 years+ in gallery conditions – with no color shifting or fading, to stay vibrant and true. 

This comparison test shows the behavior of our pigment-based ink (top) and a traditional dye-based ink (bottom) after the right hand sections are exposed to light for the equivalent to 50-100 years. 

*Metallic pigments are naturally less lightfast

Acrylic Ink FAQs

Other artists have asked us...

  • I’m not familiar with the name Rubine in artist colors for the Acrylic Ink color Rubine Red. What does it mean?
    Rubine is an adjective formed on the ruby gem name.
  • If I mix fluorescent colors together, will they still be fluorescent?
    Fluorescents have a great visual impact when combined, though the mixes will not be fluorescent
  • Do the Liquitex fluorescent colors glow?
    Yes, under ultra-violet light and a black light, the Liquitex fluorescent colors will glow.
  • I see a lightfastness rating of NR on the fluorescent and iridescent colors. What does this mean?
    For lightfastness, NR means “Not rated” – meaning that it has not been tested by ASTM for lightfastness. ASTM D4303 is the test method for Lightfastness for pigment-based artist materials. Fluorescent dyes and color coated micas are not usually in scope for this test as they are not real pigments with Color Index as such. Fluorescent colors by their very nature are dye based, they are known to be fugitive and cannot withstand the negative effects of UV light like most pigments.  This pertains to all fluorescent colors and has nothing to do with a professional or student range of art materials. We do our own in-house Blue wool test for Permanence rating where we test all our colors.
  • What should I use to create rich glazed effects?
    We recommend using transparent colors from our Acrylic Ink or Soft Body ranges mixed with our Professional Glazing Medium.
  • Can I use your Acrylic Ink in my calligraphy pen?
    Yes you can. You should flush it out with our Pen Cleaner after use, before the ink dries in the nib.
  • Is Acrylic Ink a paint or an ink?
    Our Acrylic Ink is a very fluid acrylic made with very finely ground art pigments.
